“…Fenton process (FP), using an aqueous mixture of Fe(II) and H 2 O 2 that produces ·OH, has been proved to be one of the most promising advanced oxidation processes due to its high oxidation power, rapid oxidation kinetics, and easy operation. Moreover, the inorganic reactions involved in Fenton-mediated oxidation are now well established (Table 1; Zahorodna et al 2007;Villa et al 2008;Laine and Cheng 2009). Nowadays, FP has been used for treatment of a variety of wastewater and soil containing aromatic amines, phenols, dyes, pesticides, toxic, and biologically refractory organics (Grymonpré et al 2001;Sajiki and Yonekubo 2004;Catalkaya and Kargi 2007;Katsumata et al 2008), but scarcely in hazardous solid waste.…”

Semi-solid Fenton process (SSFP) was firstly conducted on hazardous solid waste detoxication. Batch tests, Box-Behnken designs, and response surface methodology were applied to optimize the key factors including the pH, the initial Fe(II) content, and the liquid-to-solid ratio (L/S). It shows that the optimal pH, the initial Fe(II) content, and the L/S in SSFP are 3.5, 0.062 mol kg −1 dry weight and 1.77, respectively. Correspondingly, the removal efficiencies of ONA and ArNH 2 are 98.5±0.5% and 100% which agree well with the results of an established polynomial model. It suggests that SSFP is an efficient and environmentfriendly method for hazardous solid waste detoxication without wastewater generation.

“…The spent resins are important wastes in the nuclear facility operation [3], which is used for purification of radioactive wastewater, recycling of nuclear fuel and so on. Resins suffered from agents oxidizing, high temperature, catalytic effect of metal ions, adsorbed species [4] and mechanical destruction, which could lead to deterioration of the structure of resins [5].…”

“…In addition, these processes are performed at room temperature and pressure . AOPs produce hydroxyl radicals (HO ● ), highly reactive and unselective oxidants, appropriate for decomposing various organic compounds . These species have the second highest standard reduction potential, only lower than that of fluorine, and react with a multitude of compounds by second order reactions with very high rate constants (10 9 –10 12 L · mol −1 · s −1 ).…”

Degradation of bisphenol A by the UV and UV/H₂O₂ processes: Evaluation of process variables through experimental design

2017

UV‐based technologies have been proposed for the treatment of wastewater containing bisphenol A (BPA), a toxic, endocrine‐disruptor pollutant. Nevertheless, the evaluation of the role of process variables through experimental design has not been previously addressed. In this study, the effects of BPA and H2O2 initial concentrations, and specific photon emission rate (EP,0) on BPA degradation by the UV and UV/H2O2 processes were investigated, using the Doehlert design and response surface analysis. The experiments were performed in a tubular reactor equipped with a 254‐nm UV lamp, for [H2O2]0 and EP,0 in the ranges 1.6–9.6 mmol · L−1 and 0.87 × 1018–3.6 × 1018 photons · L−1 · s−1, respectively. Photolysis ([BPA]0 = 10–50 mg · L−1) was shown to be inefficient for BPA degradation and mineralization, with pollutant removals lower than 55 %. The specific BPA photolysis rate and BPA removal decreased with increasing [BPA]0. In contrast, all the UV/H2O2 experiments ([BPA]0 = 50 mg · L−1) resulted in total BPA degradation after 60 min of irradiation. In this case, the best conditions were [H2O2]0 = 7.6 mmol · L−1 and Ep,0 = 3.6 × 1018 photons · L−1 · s−1, achieving the highest BPA degradation rate and removal after 15 min, and the second highest TOC removal after 180 min. In most experiments less than 75 % TOC removal was achieved, with 95 % mineralization observed solely for the highest [H2O2]0 and EP,0. In any case, the residual toxicity and endocrine activity of treated solutions must be determined, in order to prove the applicability of the UV/H2O2 process for real water and wastewater treatment.
